    This carrier looks top notch. Only reason I did not give 5 stars is because I have not used it as of yet. Only wish I had ordered this item a long time ago. However 5 stars to Integrity, excellent service and prompt shiping. I did not expect to receive the free pmag that cam with this carrier, I live in a state that restricts everything. Upon opening the box, there was a 10rd pmag 🙂

    Thanks to everyone @ customar15

    I purchased the bolt carrier, and matched it with a nickel boron bolt I had left over from 6.5 grendel build. I totally love this bolt carrier, its fit and finish is one of the best i have seen. I have bcg’s from ares armor, psa, dsa, rra, delton, dpms and spikes, this one ranks right at the top. You can’t go wrong with this one, properly staked, and ready to work.

    This is the one to get. The full auto M-16 BC that has the increased surface bearing area (easier on your upper receiver). The EXO NiB coating is very high quality and has not flaked or chipped to date (one year of heavy range use). Personally, I like to put a very light coat of synthetic high temp grease on the four receiver slot bearing areas on the BC. I also lightly grease the charging handle rail area.
